Trigger is getting a mutation

• error trigger table to strange mutation...

  I don't think I should receive a trigger for changing table error...
  As my trigger code is just acessnig value from another table... using a function.

  The trigger table mutation should only occur when you query on the same table... The table here are different... so I don't think

• Table and how to get the mutation

  Hello friends,
  
  I am unable to understand the changing error and how to get back on it.
  
  Having read some of the documents but could not able to understand real-time scenarios...
  
  Can someone help me understand the changing error by providing a good example and how to avoid this problem.
  
  Appreciate your quick response.
  
  Thanks /.

  Transfer error occurs when you try to query the table even who wrote you the trigeer for DML triggers.

  Resolution will be different for different scenarios.

  1 if possible - avoid select / update the table even on the trigger. Try to use: new /: old.
  2. you do not have the choice to avoid the sql on the same table, you have a working arouond.

  Write a package with 2 processors, one with parameters and others do not have parameters. and the package should have a few global variables to access the arrays of values.

  Write a rowlevel of triggers and the value: new.values to with parameterized procedure, procedure 1 will affect you all these parameters to global variables.

  write a statement-level trigger calls the second procedure that will make the necessary applications / action for you.

• E-mail Trigger - cannot get data

  I searched using the e-mail triggers for information by email (the account ID and the Message ID of the message)...

  void HeadlessApplication::onInvoked(const bb::system::InvokeRequest& request)
  {
  
      QByteArray requestData = request.data();
      QVariant list = jda.loadFromBuffer(requestData);
  
      QVariantMap listMap = list.toMap();
      QString accountID = listMap["account_id"].toString();
      QStringList messageIDs = listMap["trigger_data"].toStringList();
      QString messageCount = QString::number(messageIDs.count());
  
  }
  

  I have the code above, which is triggered on receipt of an email.

  Now, if I out accountID, this reflects the ID of account as expected.

  If I pulled out a string of messageIDs, I get nothing - but if I exit the messageCount variable, which must contain the number of entries messageIDs, I get 1.

  I access the evil trigger_data?

  I looked at https://developer.blackberry.com/native/documentation/device_platform/headless_apps/triggers.html and there is little information on this I find no examples specifically for the relaxation of the e-mail.

  Thank you!

  If anyone is interested, I managed to solve this problem by using the code below:

  QByteArray requestData = request.data();
  
  //test data
  //QByteArray requestData = "{\"account_id\": 1429008735, \"trigger_data\": [[19443, \"13469\", 5], [19444, \"13470\", 5]]}";
  QVariant list = jda.loadFromBuffer(requestData);
  QVariantMap listMap = list.toMap();
  QString accountID = listMap["account_id"].toString();
  QVariantList messageList = listMap["trigger_data"].toList();
  
  //output (QString)messageList.count() + " message(s) received.";
  
  int messageNumber = 1;
  foreach (QVariant message, messageList)
  {
            QVariantList messageListContent = message.toList();
            QString messageID = messageListContent[0].toString();
            QString conversationID = messageListContent[1].toString();
            QString folderID = messageListContent[2].toString();
  }
  

  This will make a loop through all the elements and retrieve the message ID, chat and file for each message.

• Database trigger to get the value of Variable forms... How... ??

  Hello
  
  I have a global varibale in a form having a block of the base table. I created a trigger on the base table data after deletion/update, it will include all the updates/delete lines in the Table of Trail.
  
  I want to insert this global variable (which is available in the form) in the Trail Table as well as all other values of the record with the database trigger. But this global variable is available in the form not available in the database trigger. How to pass this variable to database trigger...
  
  
  Help, please...
  Thank you and best regards.

  Hello

  Package variables are specific session.

  If user1 is

  In the other schema user2
  PAK_TEST.lv_user will always be the null value.

  Locking won't, if you commit records using the trigger.

• Table mutation/trigger error

  Hello guys,.
  
  I have this problem that drives me crazy. I need to create a trigger that updates the customer's account balance. I have ACCOUNTS CUSTOMER and table of RENTAL table.
  
  When clients delete access to its relaxation program must:
  
  1 count how many DVD not returned after 60 days.
  2. multiply the number of these $25 DVD.
  3 - update the account balance.
  
  create or replace

  Dear user!

  First let me tell you that your problem has been asked more than 100 times in this forum. So for the future please use the forumsearch searching for information.

  Now let's talk about your problem with the trigger. The problem is that you are not allowed by oracle to query the table that triggers a ROW FOR EACH shot. This means that you cannot SELECT customer in the table in your trigger line. To avoid such a situation, you need to use two triggers and a temporary table.

  1.) create a temporary table to hold the value programm_id.

  CREATE GLOBAL TEMPORARY TABLE arguments
  (
    programm_id   NUMBER
  )
  ON COMMIT DELETE ROWS;
  

  2.) create a row After trigger to get the value of: new.programm_id

  CREATE OR REPLACE TRIGGER trigger1
  AFTER UPDATE OF PROGRAM_ID ON CUSTOMER
  FOR EACH ROW
  BEGIN
  INSERT INTO arguments
  VALUES (:new.programm_id);
  END;
  /
  

  3.) create a trigger after statement

  CREATE OR REPLACE TRIGGER trigger2
  AFTER UPDATE OF PROGRAM_ID ON CUSTOMER
  DECLARE
  CUSTOMER_ID_ARG NUMBER := 0 ;
  DVD_NUMBER_ARG NUMBER := 0;
  TOTAL_BAL_ARG NUMBER := 0;
  PROGRAMM_ID_ARG NUMBER := 0;
  BEGIN
  SELECT programm_id INTO programm_id_arg FROM arguments;
  
  SELECT CUSTOMER_ID INTO CUSTOMER_ID_ARG
  FROM CUSTOMER
  WHERE PROGRAM_ID = PROGRAM_ID_ARG;
  
  SELECT COUNT(dvd_id) INTO DVD_NUMBER_ARG
  FROM RENTAL
  WHERE RECEIVING_DATE IS NULL
  AND CUSTOMER_ID = CUSTOMER_ID_ARG;
  
  TOTAL_BAL_ARG := DVD_NUMBER_ARG * 25;
  
  UPDATE ACCOUNTING
  SET ACCT_BAL = ACCT_BAL + TOTAL_BAL_ARG
  WHERE CUSTOMER_ID = CUSTOMER_ID_ARG;
  END;
  /
  

  This should solve your problem (sorry did not have the time to test it!).

  Yours sincerely

  Florian W.

• The mutation of error in PL/SQL... can not find a solution

  So I have this table:
  
  create table weight)
  ident done int refers to users.
  date of dateW,
  float weight,
  primary key (ident, dateW)
  );
  
  I have a function called BMI who given a userid (ident) calculates the BMI (body mass index) based on the height of the user (it's on the users table) and the weight of the user is put on the table of characters. The feature works very well. Now I want to relax that when the user inserts a new weight, the trigger checks BMI of this user and see if it to reasonable values. I have this:
  
  create or replace
  relaxation BMITG
  After the insertion on the WEIGHT
  for each line
  declare
  int ident;
  Start
  ident: =: new.ident;
  If BMI (ident) NOT BETWEEN 17 AND 25
  then DBMS_OUTPUT. Put_line ('bad BMI');
  end if;
  end;
  
  The trigger compiles fine, but when I try to insert weights I get:
  
  Error from the 1 in the command line:
  insert into a values (1, to_date('2013-01-30','yyyy-mm-dd'), 73) weight
  Error report:
  SQL error: ORA-04091: table MyDB.WEIGHTS is changing, function of triggering/can not see

  * Cause: A trigger (or plsql user-defined function that is referenced in)
  This statement) attempted to watch (or modify) a table that has been

  * Action: Rewrite the trigger (or function) so it does not read this table.
  
  I'm not so sure about the DBMS_OUTPUT. PUT_LINE. Which function to use to alert a user that the BMI is not good? I'll need to convey this message to a Web site through apache/php
  
  Kind regards
  Daniel

  A level trigger line on WEIGHT cannot query the table of CHARACTERS (or call a function that queries the table of CHARACTERS). In doing so, as you've found, will trigger an error table mutation.

  I'm not sure I understand why you should query the table of CHARACTERS, however. If you insert a row into the table of CHARACTERS, which is the line with the weight that you want to use for the calculation, which is probably be the line with the last DATEW or not (if you insert never back-dated lines DATEW, then the line you insert is the line you want to use for the calculation and the line with the last value DATEW).

  As a general rule, I would say that the BMI function should accept a height and weight. In your trigger, you question the USERS table to get the height. Then you would spend the height and the: new.weight the new feature of the IMC.

• Changing the trigger error

  Hi all
  
  I am trying to use the trigger, but I get the mutation of error:
  
  This is my original table:
  

  BUS_CYC_D                 CYC_STRT_OF_DAY_DT        BUS_CYC_STAT_C CYC_END_OF_DAY_DT         CCUR_N                 CRE_T                     CRE_USR_ID UPD_T                     UPD_USR_ID

  I wrote a trigger to avoid insertion of a date 'ACTIVE' user. My trigger is defined as:
  

  CREATE OR REPLACE TRIGGER trg_bus_cyc_valid_br
  BEFORE INSERT
  ON t_bus_cyc
  FOR EACH ROW
  
  DECLARE
   
  
  pctx                          plog.log_ctx := plog.init('Trigger.trg_bus_cyc_valid_br');
  v_unit_context                VARCHAR2(1500);
  v_count                       NUMBER(10,0) := 0;
  raiseexcp                           EXCEPTION;
  
  BEGIN
  
      
  --    v_unit_context := 'Fetch if t_bus_cyc table already have active record'; 
        
       SELECT COUNT(1) 
       INTO v_count
      FROM t_bus_cyc tbc
      WHERE tbc.bus_cyc_stat_c ='ACTV';
       
  --     v_unit_context := 'Fetch if t_bus_cyc table already have active record'; 
       
       IF :NEW.bus_cyc_stat_c = 'ACTV' AND v_count = 1
       THEN
            RAISE raiseexcp;
      END IF;
       
    --  plog.setendsection(pctx,'SECTION_1');
  
  EXCEPTION
       WHEN raiseexcp
       THEN
            RAISE_APPLICATION_ERROR (-20000,'DUPLICATE ACTIVE DATES');    
  
  END  trg_bus_cyc_valid_br;

  But when I try to use something like, I get the error transfer:
  
  

       INSERT INTO t_bus_cyc
            (bus_cyc_d,
             bus_cyc_stat_c,
             cyc_strt_of_day_dt,
             cyc_end_of_day_dt,
             cre_usr_id,
             upd_usr_id)

              'INACTVE',
              max(bus_cyc_d) -1,

              'A',
              'A'
       FROM t_bus_cyc where bus_cyc_d = '08-DEC-08'  

  Please something to avoid the mistake of the mutation.

  Hello

  I think I misread your original message, and I changed it when you answered. My apologies.

  It looks like all this you want to do is raise an error if someone tries to add a second line "ACTV.
  You better not to use a trigger while: more it can be done with a unique index, LIKE THIS:

  CREATE UNIQUE INDEX     t_bus_cyc_actv
  ON t_bus_cyc ( CASE
                 WHEN  bus_cyc_stat_c ='ACTV'
                 THEN  1
              END
            );
  

  In general, when you have the choice of doing something with a trigger or some other way (such as a constraint or an index), then the other way is almost always better. Etbin statement "triggers are evil" is perhaps a little exaggerated, but it is something short and catchy to remember.

  The error you are getting now is that a FOR EACH ROW trigger on t_bus_cyc cannot reference t_bus_cyc himself.
  The link I posted shows different ways to get around that. As Peter says, none of them are really the best solution for your problem.

• Two tasks to trigger a simple analog trigger signal

  I use the 6351 and have two tasks:

  AnalogInputTask has 3 channels of I

  AnalogOutputTask has 1 channel AO

  When I created these two tasks to trigger a single digital channel, I have no problem. But when I want to use an analog trigger, I get error 50103 during the second task (no matter the order in which they are in) is engaged. Are there restrictions with the implementation of an analog trigger?

• Error 1074397153 has occurred to IMAQ get buffer

  Hello.

  I seem to have a problem with my camera Sony XC-EI50.  I use map of 1410 and trying to trigger outside to capture an image (using the FPGA, which is not really relevant here).  I have the adapter for camera DC-700, the trigger signal is connected to the BNC TRIG of entry.  The camera DIP switches are configured so that only 7th and 8th switches are turned on, while others are OFF.  Video output 1 is connected to the framegrabber, and the image is acquired via channel 1.

  Capture of the camera and snap features work perfectly in MAX, but I can't seem to use the Sony XC-EI50 CIM file, which could be the cause of the problem.  I get an error message when you try to load, so I use the RS-170 instead file.

  Is attached a simple .vi that I wrote it just to get the camera to work.  I run it and send a before trigger the 'get buffer vi' is to expire.  Then, I get a "error-1074397153 occurred at IMAQ Get Buffer.vi.

  
  

• Trigger - use one to create primary key values

  I'm stuck on a simple use to do a TRIGGER that fires when you add new rows to a table and want to Developer SQL to add the primary key value.

  I seem to be able to relax, but it is not inserted the primary key but giving a SQL error: ORA-00947: not enough values.

  Here's what I have.

  CREATE TABLE HF_fishers

  (

  contact_id INT NOT NULL

  , name VARCHAR (25)

  , last_name VARCHAR (35)

  PRIMARY KEY (contact_id)

  );

  CREATE SEQUENCES HF_fishers_seq.

  Then I ran the following trigger:

  CREATE

  HF_fishers_seq_trigger RELAXATION

  BEFORE INSERTING

  ON HF_fishers

  FOR EACH LINE

  BEGIN

  IF (: new.contact_id IS NULL)

  THEN

  : NEW.contact_id: = NVL (: NEW.contact_id)

  HF_fishers_seq. NEXTVAL

  );

  END IF;

  END HF_fishers_seq_trigger;

  =============

  Then I executed the following SQL statement that gives the error.

  INSERT INTO HF_fishers VALUES('Jacob','Muller');

  But if I do everything is good except that it defeats the purpose of relaxation.

  INSERT INTO HF_fishers VALUES(1,'Jacob','Muller');

  MySQL has a nice 'AUTO_INCREMENT' command, but from what I understand in Oracle, I need to set up a trigger to automatically increment a column/cell, which in this case I use for the PRIMARY KEY.

  OK Jaramillo, I tried as you wrote, but what would be an INSERT statement correct?

  -After the code trigger of Jaramillo

  INSERT INTO HF_fishers (first_name, last_name) values ("Jesse", "Owens"); -I have the trigger but he made the mistake of duplicate key.

  INSERT INTO HF_fishers values (hf_fishers_seq.nextval, 'Jesse', "Owens");  -No trigger but get key duplicated,.

  INSERT INTO HF_fishers VALUES(:NEW_contact_id,'Jesse','Ownes'); -works without the trigger but the "get links" dialog box appears. So not much 'automatic' on this issue,.

  My mistake.  Here is the modified version of the trigger. I removed the CONDITIONAL clause and comes to be a part of the body of the trigger.

  So, I created the table, the sequence, the relaxation and ran the first two insert statements and it worked fine.  The third one you have invites SQL + or any tool you use to enter a value if she sees the ":" colon as a variable binding.  Colon only works in a trigger without asking for confirmation.

  Here is the code and my exit I ran home

  DROP TABLE hf_fishers CASCADE CONSTRAINTS PURGE;
  DROP SEQUENCE hf_fishers_seq;
  
  CREATE TABLE hf_fishers
  (
  contact_id   INTEGER NOT NULL
  ,first_name   VARCHAR(25)
  ,last_name    VARCHAR(35)
  ,PRIMARY KEY (contact_id)
  );
  
  CREATE SEQUENCE hf_fishers_seq;
  
  CREATE OR REPLACE TRIGGER hf_fishers_seq_trigger
     BEFORE INSERT
     ON hf_fishers
     FOR EACH ROW
  BEGIN
  
     IF(:NEW.contact_id IS NULL) THEN
        :NEW.contact_id := hf_fishers_seq.NEXTVAL;
     END IF;
  
  END hf_fishers_seq_trigger;
  
  INSERT INTO hf_fishers(first_name, last_name)
       VALUES ('Jesse', 'Owens');  -- Works with the trigger
  
  INSERT INTO hf_fishers
       VALUES (hf_fishers_seq.nextval, 'Jesse', 'Owens');  --Works without using the trigger body code.
  
  SELECT *
    FROM hf_fishers;
  
  COMMIT;

• Update of several rows of the same table using trigger

  Hello

  I have the following table

  ---------------------------------------------------------------------------------------------------------

  CREATE TABLE ATT_PERMISSIONS
  (
  DATE OF PRMONTHYR,
  EMPID	NUMBER (10)	DEFAULT VALUE 0	,
  FROMDATETIME	DATE		,
  TODMTFDATETIME	DATE		,
  NUMBER OF PERMMINS (3),

  SSLINASTRETCH NUMBER (3).

  PERMATTINELIGIBLE	NUMBER (1)	DEFAULT VALUE 0
  );

  ------------------------------------------------------------------------------------------------------

  I want to update the column PERMATTINELIGIBLE in the same table when each line is inserted.

  I created following trigger for that

  CREATE OR REPLACE TRIGGER SSL_AFTER_UPDATE AFTER UPDATE ON ATT_PERMISSIONS

  FOR EACH LINE

  BEGIN

  Update ATT_PERMISSIONS set PERMATTINELIGIBLE =

  (

  SELECT THE CHECK BOX

  WHEN PERMMINS < = 60

  or

  (

  PERMMINS < = SSLINASTRETCH

  AND

  COUNT (CASE WHEN PERMMINS = 0 THEN NULL OTHERWISE 1 END)

  COURSES (PARTITION BY empid, prmonthyr) < = 1

  )

  THEN 1

  0 OTHERWISE

  END

  FROM ATT_PERMISSIONS where prmonthyr =:new.prmonthyr, empid =:new.empid

  ) where prmonthyr =:new.prmonthyr, empid =:new.empid;

  END;

  ---------------------------------------------------------------------------------------------------

  That is to say.

  When a row is inserted the PERMATTINELIGIBLE of all records for this employee for the month is recalculated.

  There would be only two or three records for an employee for a month.

  PERMMINS is the number of minutes to use as short leave.

  If it is less than 60 is eligible for the bonus to attendance for this employee.

  If this isn't normally the date is not eligible for the attendance for this employee premium.

  but an exception is that if a short leaves of DISP employee allowed a month (IE. ( SSLINASTRETCH ) in a straight line, IE. one day, that day is eligible for the bonus of presence.

  That is to say. Why the number of short leaves in a month is taken. If it's one and done minutes use is lower to SSLINASTRETCH, then the day is eligible for the attendance bonus.

  But when I try to create the trigger I get error, PL/SQL: ORA-00907: missing a right parenthesis.

  Help, please

  I use oracle 10g

  I want to update the column PERMATTINELIGIBLE in the same table, when each row is inserted.

  No - you do NOT want to do in a trigger.

  You cannot query the same table that the trigger is activated on. -C' is a MUTANT and you will get an exception.

  When a row is inserted is recalculated to the PERMATTINELIGIBLE of all the records for that employee for that month.

  You can not do in a trigger. Even if correct you this error of syntax, you will get the exception that I mentioned above.

  Oracle is a multi-user system. Other users can modify the same table that you use.

  So even if you could try to interview "all the records for this employee" some of them may be locked if other users access them. Also, an insert statement could try to insert two rows for an employee and the trigger could not have seen the other lines still.

  If you want to work with data SETS (all records for an employee), you must write the PL/SQL code that LOCKS all lines updated to prevent others to interfere.

  Then you make your operations but NOT in a trigger. Perform inserts and then use an UPDATE query to set this value.

  Then VALIDATE to unlock the lines.

• Best way to query - filters vs. get() cache?

  Hello
  
  I'm in a dillemma. Whether to use the methods NamedCache.get () or entrySet (filter) to query the cache. Please guide me...
  
  My understanding is that when using
  
  1. get() or getAll(), consistency checks if the entry is in the cache, if it does not exist in the cache, coherence get his from the data store
  2. simply entrySet (Filters), consistency checks the cache, and returns the results based on what is available in the cache.
  
  In this case, is it not better to use get instead entrySet in a case where we do not know if up-to-date data are available in the Cache?
  
  1. What is the difference between using a get and entrySet ?
  2. How do we make sure that up-to-date data are available in the cache when the use not a writeback scenario?
  
  I'm newbie... Gurus, please guide me...

  Thank you, Robert.

  So the air if I the search parameter is identical to the key, then its better to use get or count with all

  Currently, I have a set of expiry-delay of 1 min on the Cache. So, this extract the expired data from the data store. Are there any trigger to get out of the box of coherence mechanisms?

  I'm not sure that what you call the extraction of trigger mechanism.

  Consistency can make periodic updates cached entries that have recently been consulted within a configurable time thanks to its cooling function in advance. You can read about it at http://wiki.tangosol.com/display/COH35UG/Read-Through%2C+Write-Through%2C+Write-Behind+and+Refresh-Ahead+Caching#Read-Through%2CWrite-Through%2CWrite-BehindandRefresh-AheadCaching-RefreshAheadCache

  If this is not what you're after, would you care to elaborate a little bit on what you need?

• Insert or update trigger by passing the value to the stored procedure

  My task is to write a trigger that will pass a value for an insert or update to a stored procedure.
  
  It's Friday and I am not clear thinking, forgive me...
  
  
  Create or replace trigger < name of the trigger >
  
  After you insert or update table XXX
  for each line
  
  
  Run the Just_Do_It procedure
  (userid = new.user_id).
  
  
  If the table XXX has the userid column, and I want the trigger to get it and send it to Just_Do_It.
  what Miss me?
  
  Thank you.

  CREATE OR REPLACE TRIGGER trigger_name
    AFTER INSERT OR UPDATE ON table_name
    FOR EACH ROW
  BEGIN
    just_do_it( :new.user_id );
  END;
